If you want to double your fun with multiple vibrating cock ring options, Shag Factory Couples' Rings are just the ticket. Big Ben (purple) is the single-vibrator option, designed to vibrate against a woman's clit while the ring is worn around the penetrating penis/dildo; Double Decker (red) boasts two vibrators, so vibration can be felt on the clit AND on the wearer's balls/perineum. Both models offer three vibration speeds, up to 90 minutes of vibration before battery replacement, soft and stretchy rings, and removable vibes for ease of cleaning. And who can resist the adorable Austin Powers-esque packaging?
